Deve, your right on. Some of the best money I ever spent was for my Drill Doctor. Over the years I've collected several of the same drill bit sizes and would pitch them aside and go buy a new one. My eye sight won't let me sharpen them anymore on a bench grinder. With the Drill Doctor I realized, again, what a pain it is to try drilling holes with a dull bit. Why make it hard on ourselves?
(Best part is I knew a guy who worked at Granger and he got my Doctor at a good discount)
